Specification of Letters Patent.

Patented April 6, 1909.

Application filed February 15, 1908. Serial No. 6,074.

1 '0 all whom it may concern:

Be it known that 1, WILLIAM J. HiLLs, a citizen of. the United States,residing at Waterford, in the county of Erie and State of Pennsylvania,have invented certain new and useful Improvements in a Combinedl/Vindow-Sash Lift and Look; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, forming part of this specification.

My invention relates to win dow-sash locks, and has for its object theconstruction of a combined window-sash lift and lock, which is unlockedby the operation of lifting the sash thereby.

The features of my invention are hereinafter set forth and explained,and are illustrated in the accompanying drawings in which:

Figure 1 is a view in elevation of a portion of a window-frame and sash,showing my combined sash-lift and lock thereon. Fig. 2 is an enlargedview in elevation thereof. Fig. 3 is a transverse section of the lowerrail of a window sash and a win dow-sill showing a side view inelevation of the combined window-lift and lock shown in Figs. 1 and 2.Fig. i is a like view of the same showing a modified construction of myimproved lock. Fig. 5 is a side view in elevation of the window liftportion of my invention.

In these drawings A indicates a window frame, and B the lower rail of awindow-sash.

Upon the inside of the lower rail B I loosely secure one or moresash-lifts G the upper end thereof being curved as shown in the drawingsto form suitable finger holds whereby to raise the sash B. The lower end0 of the lift 0 extends downward nearly to the window-sill A where itterminates in a beveled face 0 and a hooked shoulder c on the side ofthe lift next to the window sash B. The lift C is secured to the sash insuch a manner that the lower end 0 thereof can be swung to and from thesash-rail, and the thereby leaving some space for play between the screwhead and the sash-lift and rail. To insure this freedom of action on thepart of the sash-lift C, I make the lift C with a curve 0 at each edgeat a point adjacent to the openings for the screws D in order to reducethe required play between the screw head D and the sash-lift C to aminimum.

To complete the locking mechanism I secure to the sill A of the windowframe, a catch a, preferably as shown in Fig. 3, but it may be securedon the top of the frame sill as shown in Fig. 4. The hooked upper end ofthis catch (t is also provided with a beveled face 0; in order to shuntthe lower end of the lift C backward so that its hook 0 vii] catch underthe hooked upper end of the catch a.

In operation when a window provided with my combined sash lift and lockis closed down the hook c on the lower end of the sash-lift engages thehook on the upper end of the catch a secured to the window-sill A andsecurely resists all efforts to raise the sash otherwise than by liftingon the sash lift C. When it is desired to raise the win- (low-sash, thelift 0 is grasped by the lingers and the strain exerted thereon to liftthe sash will cause the lower end 0 thereof to swing outward from thesash rail B thereby drawing the hook c thereon out of engagement withthe catch a and allowing the win dow sash to be lifted.

Having thus described my invention so as to enable others to constructand use the same, what I claim as new and desire to secure byLetters-Patent is:

1. In a combined window-sash lift and look, a sash-lift having openingstherethrough, a downwardly projecting arm on said lift adapted to swingaway from the window-sash when upward pressure is exerted on said lift,screws passing through the openings in said lift and into the windowsash so as to permit the lift and depending arm thereon to swing on saidscrews, and means secured to the window-frame adapted to projectupwardly between said depending arm and the window-sash and engage saidarm when the window-sash is closed down so as to prevent the same frombeing raised. without being first swung away from the window-sash,substantially as set forth.

2. In a combined window-sash-lift and look, a sash-lift having a curvedupper end adapted to be grasped by the fingers of the be disengagedtherefrom when upward presoperator, curved portions 0 screws passingsure is exerted on said lift, substantial y as through said liftsadjacent to said curved and for the purpose set forth.
